Hi fellow simmers, i've got the same OAT issue even with the SP2 update of the PA46T.
Bert, could you tell me where to find your updated G500? i tried the one available in the AVSIM file library "Carenado P46T Malibu G500 Mod" posted by Henry.
It add some great features but do not allow OAT to work.
I would be glad to get the right version.
And yes, thanks to men like Bert & Bliksimpie for making thoses birds better!
Best regards,
Patrick
